CIRCULATORY SYSTEM
It is a set of organs that make the blood travel through the body, to distribute substances and oxygen nutrtivas

Anatomy:
-Heart: A muscular organ, is located in the thorax between pulomnes, has the shape and size of a fist, is comprised of 3 layers (Pericardium, External - Myocardium, Endocardium)
"Blood vessels: arteries, veins and capillaries

Internal structure of <3
"This divided into 4 chambers
"In the top 2 are called atria, chambers that act as receptor
-At the bottom there are 2 ventricles. cameras act as propulsion

Atrioventricular valves have holes that allow the trail of blood in one direction

Heart function: to pump blood through the body continuously
Blood: red and viscous fluid flowing through the arteries and veins of the body
Composition of blood:
-Solid component (40%)
-Hermaties-red blood cells, erythrocytes
"White Blood Cells: WBC
-Platelets - Trombositos

Liquid Components: Plasma

Systole: The movement of contraction of the heart and arteries to push the blood to the blood vessels
Diastole: is the movement of expansion which makes the heart to keep blood

Circulation Minor: the trip by the non-oxygenated blood
Circulation Staff: This is the journey that makes the blood oxygenated

Veins:
Museulares-thick-walled vessels
-Responsible for distributing oxygenated blood

Arteries:
-Glasses responsible for collecting the blood is not oxygenated
-Resistant walls


BLOOD

Erythrocytes:
Disc-shaped cells
No nucleus
Pigment. HEMOGLOBIN
Function: capture O 2from the lungs and carry it to other cells, where CO 2collected and brought to the lungs

Leukocytes:
They are variably
Present Core
They have no pigment
Function: defend the body against disease
Perform movement Diapedesis (Diapedesis: the movement of leukocytes from the blood into infected tissues)
Types of Lymphocytes and Granulocytes

Thrombocyte:
Function: act in the process of blood clotting, bleeding to avoid an injury

Haemophilus: the inability to clot blood

Cardiac Physiology:
Diastole: entry of blood to <3
Systole: output of blood to <3
